This premium Neodymium Block Magnet measures 21mm long x 13mm wide x 8mm thick and is manufactured from ultra-powerful N50 Grade Neodymium (NdFeB), one of the strongest commercially available permanent magnetic materials. Magnetised through its 21mm length, this compact magnet delivers an impressive 4825 Gauss surface field and a substantial 11.3kg pull force, making it ideal for applications where maximum magnetic strength is required in a small footprint.
Identified by AMF Magnetics Part Number 22051, this high-performance rare earth magnet offers an exceptional power-to-size ratio and is suitable for industrial, engineering, scientific, manufacturing, and DIY applications.

AMF Magnetics Part Number: 22051
Common Applications
The combination of compact dimensions and high magnetic strength makes this neodymium block magnet suitable for a wide range of professional and hobbyist applications, including:
Engineering and product development.
Industrial manufacturing and assembly.
Scientific research and laboratory experiments.
Magnetic fixtures and holding systems.
Automation and robotics projects.
Sensor and switch mechanisms.
Magnetic closures and latches.
Custom magnetic tools and devices.
Educational demonstrations.

Its strong magnetic field allows it to perform reliably in applications where space is limited but magnetic force is critical.
Why Choose N50 Neodymium Magnets?
Neodymium magnets are renowned for their superior magnetic performance compared to ferrite, alnico, and other permanent magnet materials. As an N50 Grade magnet, this block offers exceptionally high magnetic energy density, enabling stronger magnetic fields and greater holding force from a smaller magnet.
This outstanding strength-to-size ratio allows engineers and designers to create more compact, lightweight, and efficient products without sacrificing performance.

Important Handling Information
Due to their exceptional strength, neodymium magnets should be handled carefully. Avoid allowing magnets to snap together or collide with steel objects, as chipping may occur. Keep away from sensitive electronic devices, magnetic storage media, and medical implants such as pacemakers.
Small magnets can present a swallowing hazard and should always be kept out of reach of children.

The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.
Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.
Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
